727 Torque converter Help!!!!!!!

Hi Guys, I have a 1970 Dart Swinger with a 440 motor and 727 transmission. The motor was bored .030 with a very small cam installed (a step or two over stock). The rearend is a 3:55. I'm NOT RACING the car at all, I'm using the car as a weekend driver and driving it to different car shows within driving distance (3 or 4 hours) of my home. My question is does anyone have a suggestion of the correct size torque converter I should have in there. I currently have a 2800 stall speed from ACC and it doesn't seem to pulling out correctly, almost like it's slipping when cold. The transmission was totally rebuilt and a shift kit was installed. I'm asking if anyone knows the correct stall speed and what brand torque converter they would suggest? Any suggestions would be greatly appreciated.
Thanks Dave!!!!!!!!!!
